TO WHQM IT MAY CONCERN: y

Be it known thatV I, .IA H. SPELMANroBazetta, in the county of Trumbull,and State of Ohio, have invented certain new and useful Improvements inChu-rus; and I do hereby declare that the following is a full endVcomplete description of4 the same, reference beingv had to theaccompanying drawings, making a' part of this specification, in w hich,q

' Figure 1 is an inside View of lthe churn.

Figure 2, va. side view ot' the beaters.

Figure 3, an end view' of the same.

Like letters of reference refer to like parts in the several viewspresented.

The bodyr of this churn consists ofrau oblong square box or case, A,fig. 1, the size of which being accordigig to capacity of theclmrdvrequired. Through the centre of this box is projected a shaft, B,on which is placed a revolving beater or dasher, C, consisting of a.pair of heu-ds, E, iig. 3, secured at each end of the shaft, as sbown inthe drawing. On the arms of these heads, and reaching from one head tothe other, are secured the.beaters F, inthe order as shown in iig. 3, inwhich it will beseen that the dashers are placed on each side of thearms comprising the heads, so that each alternate one, G, may extend outbeyond the arm, whereas the other, F, on the opposite-side, dojcs notreach quite to the end; hence the two series of beaters constituting thedasher, whenirevolving, describe unequal circles one within the other.It will be observed that the arms I, fig. 2, are made slanting andreversely from each other, the purpose of which will hereafter be shown.J, fig. 3, is a slot, cut down in each arm J' to the centre, throughwhich the dasher is slipped, on to the shaft, and secured to the same bypins K. i

v'This churn is operated by the cog-wheel and pinion L, arranged on theend ofthe box, as shown in iig. I, and .as it is made to revolve-it(lashes the cream in among the beaters, the inner range H disturbing thecream near-the centre, and the outer range G disturbing it on the outerside. At the same time, by the slanting direction given to the sidcs ofthe arms I, the cream is thrown from the ends towardthe middle, bywhich, together withthe action of the grooves N, cut in the bottom ofthe churn, it smost thoroughly agitated and broken up,`whereby thebutter is easily and quickly brought. The slantng direction given to thesides of the hrms I, referred to, being reversed on each alternate arm,vthe eifect of throwing the cream toward the middle of the churn will bethe same in eithcr'way. that the dasher may be made to revolve; hencethe churn will operate equallyivell when turned in either direction.

WhatI claim as my invention, and desire to secure by Letters Patent, is

The special construction of the dasher C, with slanting arms I andbeaters G F, when arranged so as to' describe unequal circles one withinthe other, in combination with the case A, in the manner as and for thepurpose set forth.
